Same issue, after deleting emulator no issue. I’ve in parallel a real device and he didn’t got the issue. To got the issue i’ve hot reload the app quickly after payed my in app purchase subscription. Even after killing app and restarting it issue persisted, maybe something was broken.

I get this now too and reached out to support.

I’m not sure if this is happening only on the emulator or also in production.

Everything still appears to work properly, ignoring all the exceptions in the logs

Support responded and said this will be fixed in the next release:

https://github.com/RevenueCat/purchases-android/pull/2376

Hi all,

The fix has already been merged and it’s available in the 8.17.1 version of the SDK.

Best,
